Abstract
A method for preparing an exfoliated vermiculite, comprising the following steps: (a) a step of heating a non-exfoliated hydrated vermiculite at a temperature extending from 400 to 600° C. for a period extending from 3 hours to 7 hours, in this way generating a dehydrated vermiculite; and (b) a step of contacting the dehydrated vermiculite with a solution containing an intercalating agent capable of decomposing while generating gases.
